Anybody used one? I bought one in like new condition, also with a 2x flat field tele-converter and it looks pretty impressive. The guy that sold it told me he bought it many years ago for macro work. Anyone have any good or bad words about this baby? Oh yes, it came 'attached' to a black Rollei SL35 E in mint condition. I'm trying to determine if I'll keep the bugger or put it up for sale on Ebay. Any ideas will be appreciated.
